A1200 harddrive

Sounds exactly right to me...  Just a couple things to note:

On opening HD toolbox you should be presented with a list of the drive device interfaces (unless your HDtoolbox icon has a device = xxx.device tooltype set already.

Even though its an AT/IDE drive, the proper name for an A1200 HD on the internal controller is scsi.device.  That can be a bit confusing...

Partitioning is relatively hassle free and you can just drag resize partitions you are making.

Don't forget to go into the advanced options and set the "Max Transfer" sizing for each partition.  It should be set to 0x1ffff.  Otherwise, an old bug will come back and bite you in the butt.

I'm not sure any half modern drive has issues anymore but mine is still set to the value llwath mentions :-)

Exactly.  It doesn't hurt anything to change this setting, and it can save you from severe data corruption, if your drive happens to be one of the ones affected by this problem.  

I was an early A1200 owner, and had a (high-end at that time) Quantum 2.5" drive in it...  It was not a fun combination until my local dealer got a memo from C= on what needed to be set to fix the problem!  (I had tried 2 different A1200s from the store, and two different HDs, and both with and without the GVP accelerator...)  And most every filesystem available at the time...  Lotsa AmigaDOS 3.0 installing experience.  This is one setting that caused me enough pain that I'll never forget it.  ;-)
